The 'biochar' paper you reference seems to be stretching the
definitions a bit. 350C formation hits close to the bottom of the
'charring' range, 200C is low torrefaction. At 200C it is doubtful
that there would be any recalcitrant carbon present. The raw manure
performs well with lead too. This is all about phosphorus not
sorption on carbon or even surface functional groups. <br>
A rose by any other name.... <br>
but its probably my 'failure' to understand.<br>

I think it would be wise to examine the properties of biochar
generated from camel dung.<br>
If it resembles the biochar from cow manure, it could be quite
valuable.<br>
